Highly useful freeware solution to O365/Tbird meeting compatibility problem; not optimal, but worth what I paid for it (free). Gives option to download the otherwise missing ICS attachments from O365 meeting invitations, for importing into a different calendar solution (Mac Calendar, in my case). Does not work for meetings sent prior to installation of this add-on, but workaround is to forward old invites back to yourself (inline only, not as-attachment). Ideal future behavior would be for it to prompt to open ICS in default calendar application, rather than forcing download every time. Thank you, Leon!
